The Department of Health has reported that there has been a significant rise in influenza —flu — activity across Pennsylvania since Thanksgiving, with a total of 834 positive cases being reported since Dec. 8.

“Flu activity has increased from sporadic to widespread throughout the state meaning at least half of the state’s regions are experiencing outbreaks of flu or increases in flu-like illnesses,” stated a Department of Health news release.

Out of Pennsylvania’s 67 counties, Franklin has one of the highest numbers of reported positive flu cases with 30 already for the 2012-13 season.

The state’s highest reported outbreak stems from Allegheny County — home of the City of Pittsburgh — with 157 reported cases this season.

Early outbreak

“The flu made an appearance earlier this year than in most flu seasons, as widespread activity is usually not seen until January,” said the press release.

Other counties that have reported a minimum of 30 positive cases include Beaver, Berks, Centre, Chester and Montgomery.

Positive flu cases for Franklin County’s neighbors include nine for Adams County; two for Fulton County; 13 for Cumberland County; and six for Huntingdon County.

Most of the reported positive cases stem from the strain identified as influenza H3N2 — the type of flu most often likened to more severe flu seasons.

Flu shot

If you haven’t received your flu shot it is not too late to do so. “If you decided to wait, now is the perfect time to get vaccinated,” said Michael Wolf, acting secretary of health. “Ensuring that you and your family get vaccinated will reduce the chance that your holiday plans will be affected from the flu,” Wolf added.

Many individuals can receive the flu shot at their local doctor’s office or a pharmacy for a small nominal fee.

It takes about 10 to 14 days for the vaccine’s full protective benefit to kick in.
